Question about Meade ETX-90EC (325 x 90mm) Telescope

Optical mirror detached - Meade ETX-90EC Telescope

Any ideas on how to get a replacement and re-attach it. The 'scope is a 2000 model, so out of warranty - and is otherwise in perfect condition! I live in a place where I cant get it to a dealer (Grand Cayman).

Your best bet is to ship it back to Meade for repair. they may not look it but there are very close tolerances that have to be achieved and takes certain tools for alignment.

Telescope doesn't seem to work


This issue will be extremely hard to diagnose over the net but I'll give it a try. This is from Meade. The link to the online manual is below: http://www.meade.com/manuals/etx90ec/index.html Unable to see an image through the eyepiece:
  • Confirm that the lens cover has been removed from the telescope.
  • Confirm that the flip-mirror control (16, Fig. 1) is in the "up" position if using the eyepiece holder (4, Fig. 1) so that light is directed to the eyepiece (1, Fig. 1). Confirm that the flip-mirror control is in the "down" position if using the #932 Erecting Prism or doing photography with the ETX-90EC (see Telescope Controls and PHOTOGRAPHY WITH THE ETX-90EC).
It sounds like you are correct about a mechanical issue with the knob that moves the mirror. If you need a quick fix try your local camera repair or watch repair shop as the are familiar with intricate parts. The camera shop would be preferable as they know optics. Otherwise you could ship it to me and I could repair it fro you depending on the availibility of parts if parts were needed. Check my picture for my site address and get contact info there for more information.

Only Meade has parts. Usually they want you to send the scope back to them for repairs. However you can contact their customer service department and ask if they will sell you just the part:

2 small lens fell out of my telescope how do I get them back in and where do they go ??


The Meade ETX90 does NOT have small lens! It has a large curved lens in the front. and a holder for the eyepiece in the back (top). There is also a camera port in the back, and a flip lever that sends the light either straight back to a camera, or UP to the eyepiece holder.

There is an INTERNAL secondary mirror mounted on the back of the front large lens. If this fell off INSIDE, you will need to remove the front lens to fix it. NOT an easy fix as the optical alignment can get messed up when you do this.

Here is the manual for an ETX90, you should read it completely.

Meade "might" sell you the replacement part. But most likely they will want you to return the scope for repairs.

You can call Meade customer service and see if they will sell you this small part-- probably called a dovetail mount--

These can be bought from several different places if you know exactly what you need.
